You would have to validate it with a regular expression or with a manual validation of the variable with your mail chain, firebase only supports you in that it is a valid email. In the following reference you only mention the error "auth / invalid-email" link

This example is using string validation:

var idx = correo.indexOf('@yahoo.com');
if (idx > -1) {
  // verdadero si contiene yahoo.com
}
